FIELD: automotive industry; tires.
SUBSTANCE: each bead is reinforced by strengthening member consisting of at least two layers which are either turned up separately or folded in two to form four strengthening layers arranged close to one another is axial direction. Two inner axially directed layers are formed by elements parallel to each other from layer to layer, and two central axially-directed layers of member are formed by elements intersection from one layer to the other. Elements form angle within 0o and 10o with circumferential direction. Outer ends of layers in radial direction are arranged in bead at different heights so that any ring strap of bead strengthening member containing at least two layers of strengthening elements and enclosed between two parallels of pneumatic tire is formed of at least two layers of strengthening elements intersecting from one layer to the other.
EFFECT: simplified process of manufacture of tire, increased reliability of tire.
